Solution:
Step 1: Calculate the molar mass of C₃H₆O₃.
molar mass = (12.0 g/mol × 3) + (1.008 g/mol × 6) + (16.0 g/mol × 3)
molar mass = 90.048 g/mol
Step 2: Calculate the number of molecules of C₃H₆O₃.
[tex]\text{number of C₃H₆O₃ molecules = 5.0 g C₃H₆O₃} × \frac{\text{1 mol C₃H₆O₃}}{\text{90.048 g C₃H₆O₃}} × \frac{\text{6.022 × 10²³ C₃H₆O₃ molecules}}{\text{1 mol C₃H₆O₃}}[/tex]
[tex]\boxed{\text{number of C₃H₆O₃ molecules = 3.34 × 10²² molecules}}[/tex]
